Because fat soluble vitamins can be stored in the body, high intakes of these vitamins can result in harmful levels. See our vitamins and minerals table for a more complete list of some common vitamins, their functions and food sources. Minerals and trace elements are chemicals that we need in small amounts for the body to work properly.
Minerals and trace elements are mainly found in meat, cereals, fish, milk and dairy foods, vegetables, dried fruit and nuts. See our vitamins and minerals table for a more complete list of some common vitamins, their function and sources.
Generally you can get the vitamins and minerals you need by eating a healthy balanced diet. Aim to eat a variety of nutritious foods from every food group, including plenty of vegetables and some fruit each day. Vitamin D is the only vitamin that you are unlikely to get enough of from your diet as it is found naturally in only a few foods, and only in small amounts.
Well-planned vegetarian and vegan diets can be healthy diets as they are generally low in saturated fat and high in fibre.
Bupa Australia Pty Ltd makes no warranties or representations regarding the completeness or accuracy of the information. Vitamins and minerals are called micronutrients because they are needed in very small amounts.
Recommended intake levels have been developed for each vitamin and mineral to give guidance as to how much should be taken every day to prevent deficiency. Antioxidants are molecules are made by the body or found in some foods and supplements, Antioxidants protect the body by neutralizing other, unstable molecules, called free radicals, that are produced during normal cell functioning. Long-term infections such as HIV can upset this balance by causing the body to produce more free radicals than usual.
Eat lots of colourful fruits and vegetables to get the antioxidants found in the pigments and the phytochemicals contained in the whole food. Black and green tea, mushrooms, red wine and dark chocolate are also thought to be good sources of antioxidants.
Antioxidant supplements include vitamins C and E, the minerals zinc and selenium, as well as coenzyme Q10, alpha lipoic acid and N-acetyl cysteine. This table lists the RDA (recommended daily allowance), UL (upper tolerable limit) and experimental high dose, toxicity, function and food sources. This section deals with some vitamins, minerals and other nutrients that have been studied in HIV.
Consider taking a multivitamin-mineral each day.Several studies have shown that vitamin and mineral supplements can have many benefits in people living with HIV. If you get B12 shots and your vision is getting worse, mention it to your doctor, especially if you are a smoker. In people with HIV, there is some evidence that vitamin C can inhibit replication of the virus in test-tube experiments, but it is unclear what this means in the human body. Vitamin D is emerging as a very important nutrient, with more diverse functions than just its traditional role in calcium metabolism.
Vitamin D is found in some foods, but these sources generally do not provide enough vitamin D on a daily basis.
For people with HIV, vitamin D supplements are a sure way to get the recommended daily allowance.
Zinc is a critical mineral for the immune system; a deficiency can cause severe immune suppression. These and other supplements can be quite expensive and should not be seen as a replacement for a healthy diet and lifestyle.
Alpha lipoic acid is a powerful antioxidant made by the body that is used to regenerate glutathione (the major antioxidant in cells) as well as the activated form of vitamins C and E. Carnitine (also known as L-carnitine) is a natural substance found in foods and made by the body. Over-the-counter supplements may contain a version of carnitine called acetyl-l-carnitine but beware that some have very little L-carnitine in them; be sure to buy from a reliable source.
N-acetyl cysteine (NAC), a derivative of the amino acid L-cysteine, is a potent antioxidant that regenerates glutathione in the cell (see "Antioxidants and HIV," this chapter).
L-glutamine is an amino acid that is used to provide fuel for intestinal cells, muscle cells and immune cells. Probiotics are live organisms, including the bacteria Lactobacillus and Bifidobacterium species and yeasts.

This is unlikely to happen when vitamins are consumed in food, but it is possible to overdose on fat-soluble vitamins when taken in supplement form. The amount of sun exposure needed for healthy vitamin D levels depends partly on your skin type, the time of year and where you are.
These include older people, especially those who are housebound or living in aged care homes, people with darker skins, and people who wear concealing clothing.

They will be able to check your vitamin D levels and advise you if you need to supplement your level by taking vitamin D tablets. The best way to get your vitamins and minerals is from a healthy, well-balanced diet, because we absorb vitamins and minerals better when eaten as part of our usual diet.
And some vitamins and minerals, particularly fat-soluble vitamins, can be harmful in excessive quantities. The exception is vitamin B12 for vegans, as this vitamin is naturally found in foods of animal origin (e.g.
To the best of their knowledge it is current and based on reputable sources of medical research. Bupa Australia is not liable for any loss or damage you suffer arising out of the use of or reliance on the information. Some scientists and healthcare experts say that micronutrients have therapeutic value at very high doses, up to 10 times the RDA, but others disagree and prefer to take a more conservative approach. In turn, this can lead to a condition known as oxidative stress, in which the body cannot deal with all the free radicals it produces. Try to include blue, purple, green, orange, red and yellow foods to get the full complement of beneficial substances. The RDA usually includes all intake, from both food and supplements, while the UL is from supplements only. They are also important for healthy mitochondria, the power-producing structures in cells, and may help decrease the impact of mitochondrial toxicity (see "Mitochondrial toxicity," Chapter 5).
It is very effective at cleaning up molecules that damage cells and tissues (see "Antioxidants and HIV," this chapter).
The most important benefit for people with HIV is the widespread antioxidant action of vitamin C.
Also, people who live in northern climates (like Canada) probably do not get enough sun exposure to make adequate vitamin D.
Vitamin D is found in multivitamins and calcium supplements as well as individual vitamin D pills. People with poor fat absorption or malnutrition are more at risk of being deficient in vitamin E. People with chronic diarrhea, new immigrants from refugee camps and malnourished people with HIV, especially children, are at high risk of having a deficiency. Studies have shown that low selenium levels in the blood are associated with an increased risk of disease progression and death.
In some cases, the benefits of these supplements have been described in small human studies, animal studies and case reports. The dosage is not defined because it has not been studied enough or approved for these applications. It plays an important role in immunity because it helps to maintain the intestinal barrier and is a preferred fuel for various cells of the immune system. It has been used to treat congestive heart failure and gum disease (gingivitis) and may help protect the heart and nerves. Also, its Practical Guide to Herbal Therapies covers many common herbal therapies used by people with HIV.

Fat-soluble vitamins are less easily to be lost during cooking than water-soluble vitamins. You need to wear sunscreen when out in the sun during peak UV times (UV index is 3 or above). It should be used as a guide only and should not be relied upon as a substitute for professional medical or other health professional advice. Vitamins and minerals do not provide energy but perform vital functions that regulate the many activities and chemical reactions that take place inside the body. For many micronutrients, experts have also set an Upper Tolerable Limit (UL), which is the maximum daily amount a person should consume. Studies are difficult to interpret, but recent clinical trials of multivitamins have demonstrated benefits, and many healthcare providers now believe that everyone living with HIV will benefit from taking a multivitamin-mineral each day. Before beginning to take any of these supplements, be sure to discuss it with your doctor and other members of your healthcare team. B vitamins are depleted quickly in times of stress, fever or infection, as well as with high consumption of alcohol. B12 deficiency is associated with an increased risk of peripheral neuropathy, decreased ability to think clearly, and a form of anemia.
Vitamin C has been studied for cancer prevention and for effects on immunity, heart disease, cataracts and a range of other conditions. The daily experimental high dose is between 500 mg and 2,000 mg, the upper tolerable limit. And the use of sunscreen, which is highly recommended to prevent skin cancer, blocks the skin's ability to make vitamin D.
Until this is fully studied, it may be a good idea to reduce vitamin E supplements to 200 IU unless your doctor suggests you take more.
Be aware that high doses of zinc supplements in people who are not deficient can decrease immune function.

The therapeutic doses are not really known for HIV disease and recommendations given here are based on doses used for other conditions or in studies. Lipoic acid is used to treat diabetic neuropathy (a nerve condition associated with diabetes) and liver disorders, and it may also have a role in slowing the hardening of the arteries (arteriosclerosis). It does this mainly by supplying the building blocks needed by the mitochondria to make an energy molecule called ATP, the basic fuel for cells. Prescription L-carnitine is very expensive and usually not covered by insurance plans for any of these indications.
Cysteine appears to decline in people with HIV who have low CD4+ cell counts and in those with wasting (see "Weight loss and wasting," Chapter 6). Glutamine levels decline during periods of physiological stress like opportunistic infection, surgery, burn and cancer.
Microflora keep the gut healthy by preventing the growth of disease-causing bacteria and maintaining the intestinal barrier. General Disclaimer: The Body is designed for educational purposes only and is not engaged in rendering medical advice or professional services.
Outside of these times, check the Cancer Council guide to see how much sun you can safely get.
Vegans should look for foods fortified with vitamin B12 and they may also need a vitamin B12 supplement. Remember that these recommendations are set for the general population and do not take into consideration any disease state, like HIV. In turn, these deficiencies can increase the rate of HIV disease progression to AIDS and can increase the risk of dying. When making decisions about supplementation, be well informed and involve your healthcare team in your decisions. Two ways to lessen the effects of oxidative stress are to increase antioxidant intake and to decrease exposure to things that increase oxidative stress, such as pollution and cigarette smoke. Keep in mind that the RDA is very low and taking a total of 50 mg of B1, B2 and B3 will more than cover B-vitamin needs. Although vitamin C cannot cure the common cold, supplements of 1,000 mg per day have been found to decrease the duration and severity of symptoms.
Be sure to add up all the vitamin D from different supplements to be sure you are not getting too much. There are other blood tests that can help determine whether there really is an iron deficiency.
The dose recommended for diabetic neuropathy is 100 mg 3 times per day; the dosage for HIV is unknown. Most of the research suggests that carnitine has a protective effect on the central and peripheral nervous systems and the heart, probably because of its role in mitochondrial function.
NAC supplements may be able to replenish low glutathione and improve the antioxidant capacity of cells. It may have a therapeutic role in treating intestinal disease and wasting, and some people with HIV have found it to be a good treatment for chronic diarrhea. Probiotic supplements are helpful after a course of antibiotics because they replace the microflora that were damaged by the antibiotic.

For this reason it is believed that the micronutrient requirements for people with HIV are higher than the RDAs for the general population. Check the multivitamin you take; if it has 30 to 50 mg of these vitamins, you don't have to take a B-complex supplement in addition to the multivitamin.
Studies of the general population suggest that selenium supplementation may provide some protection from cancer.
It may be helpful in the treatment of peripheral neuropathy (numbness, tingling or burning in the feet and sometimes hands), dementia and mitochondrial toxicity (see Chapter 5). Study doses have been as high as 2,000 mg per day, but this is expensive and may not be well tolerated. The dose for treating diarrhea is 10 to 30 grams per day; the maintenance dose is 5 grams per day. Probiotics may also reduce chronic diarrhea and improve symptoms of irritable bowel syndrome. Iron is a pro-oxidant (the opposite of an antioxidant), which means it can damage different tissues in the body( see "Antioxidants and HIV," this chapter).
The most beneficial dose is not certain, although a dose of 500 mg per day may offer some benefit with a reduced risk of toxicity.
